The new web notifications tests in http/tests/notifications use an updated API for managing web notifications: // Web notifications support void grantWebNotificationPermission(in DOMString origin); void denyWebNotificationPermission(in DOMString origin); void removeAllWebNotificationPermissions(); void simulateWebNotificationClick(in object notification); These need to be implemented in order for the tests to work. (grantWebNotificationPermission is already ported from grantDesktopNotificationPermission).
I would like to implement this support. Will provide working patch soon.
